z claims. j (c1. 164-113) This invention is directed to an improvedlmachine for producing perforated tapes, said tapes being adapted to control in a separate machine the release of matrices and spacers of typographical composing machines, siic'h as linotype machines of the general organization represented in U. S. Letters Patent to O. Mergenthaler No. 436,532., In these latter machines, the matrices and spacers, after being released from their,

respective magazines by the operation vof 'poweru actuated escapement devices;` are composed in line and then presented lto the justifying and casting devices for themproduction of a slug orf linotype bearing on its edge a justified line of printing characters. When the machines are operated by va perforated tape, the symbols produced in the tape automatically control the opp eration of the power-actuated escapement de-` vices, each symbol representing aparticular matrix lor spacer which is to be released in vcornposing a line, and the symbols being disposed in groups or rows representative of the successive lines .tobe composed or the printing slugs 'to be cast therefrom. As is well understood, the number of symbols ineach group or row must cor`V respond, to the number ofmatrices and spacers toV be set up inthe line represented Aby thatpar ticular group, and herein lies one ofY the main dimculties in attempting to control the operation of a linotypemachine by a perforated tape, it being obvious that the actual numberof matricesand spacers which can be composed in a'linejof a 'given length will vdepend uponlthe sizefor thickness of the matrices comprising the`pa.rticuV lar Afont in use. Bearing in mind thejgreatnumbe'r of different'sizes of matrix fonts employed in linotype machines, as well as the wide variation prevailing between the individual matrices com# prising each font, it is'obviousjthat the number of symbols which should be produced in the tape to compose a given-length lineof matrices'ofa particular font is diicultlof as'certainment;

In an attempt to solvethis problem, it hasbeen proposed to associate with thenperforating ap-` paratus, for the vguidance of the lkeyboard op.- erat-or,l a counting mechanism lwhich will register and indicate, the number of units representedby thefmat'rices to be'released` by the symbols produced, but the great number rof unitswhich must be reckoned with in the case of linotype matrices (well above forty-five) as wellas the vnecessity for variations in adjustment to accord with the numerous matrix fonts employed, leadl intoso many complications as -to render the counting mechanism altogether impractical and unreliable.

While successful counting mechanisms have beeny employed in connection with perforatorsusedfor the production of perforatedtapes to control the operation of typewriters and type-casting maf chines'other than linotype machines, it must be Y remembered that the number, of units required for these machines is' comparatively small, eighteen being about the maximum kfor type#- casting'ma'chines and a'vmuchV less number for typewriters@` i f y" ,"f" j' The present invention' is intendedtofo'vercomev thev foregoing andother diiilculties and vcontemplates a simple and thoroughly reliable device bywhich the operator may determine with `ac' curacy the A exact number "of symbols w ich 15 should be made in `the-perforated` tape tofycom-V- pose a `justifiable line' of matricesand sp`a ':e`rsl of any given lengthin the case of any` selected font, so that when ,the perforated ytape is run A through a Ylinotype'machine of the tape con# T20 trolled type, itcan be relieduupojn to producea 1 justified line of typecorresponding to the characters Arepresented.v by, the; symbols producedin l the tape by theperforating machine. u ff In carrying out the inventionjit is proposed to combine with :the 'tape-perforatingf unit a` 'setf of dummy matrices or indicators, `varying"fin" thickness tol'correspond to the'rmatrlces and spacers (both the non-expansibla'as well as the expansible type VCommonly called Y fspaceba'nds) `3o of the linotypev machine to be .operated yby the perforated tape, 'and tol control ,the operation 'of both 'the' perforating unit and'dummyumatrices from a common keyboard, injsuch manner that`r asl each L symbol 4 is'f produced in the "tapeV by the actuation of ailnger key,"a dummy matrix'corr'f, responding vinA thickness to the: matrix or the spacer or the'spaceband represented by saidf'symf bol and tofbe released by it from the magazines l of the machines to be operated, is presented to' a measuring device, which measures the thicknessfjof suchjjfdummy matrix.

vThe, improved machine comprises three essential elements, namely,-aperforating unit A, a measuring unit B anda keyboard C, which ele-l ments may be modified Vas desired so long as they are made to cooperate in the manner herein set` forth. Thetapeperforating unit and the keyboard are substantially lthe same as those illustrated'infPatent'N'o. 2,002,516, granted May 28th',

1935,"to` William Ackerman,to which reference the groups being spaced apart to provide for a line of feed perforations insertedalong the center of the tape by the vertically-moving overhead punchV rod A6.

The advance of the tape is effected by means of a pair of'feed rollers A8 between which the tape is passed, the rollers being positioned one above the other on separate shafts AIO and AI I which mayf be journalled in extensions of the top guideplate AI. teeth, not shown, circumferentially positioned around the center of the roller Vand adapted to engage the feed perforations in the tape, while the upper roller A8 is provided with a peripheral groove, also not shown, butwhich serves the purpose of accommodating the fcedteeth on the lower roller.

At the front end of the shaft AI I, which carries the toothed roller, is a ratchet wheel All, with which is associated a feed pawl AIS and a retarding detent AIG, the lformer being pivotally connected to -a horizontal rocker arm AI1 loosely mounted on said shaft, and the latter being 'pivotally mounted at AI3. According to this arrangement, when the arm AI1 is rocked upwardly and downwardly, the ratchet wheel AI4 is operated intermittently by the. pawl AI5 and the tape T fed step by step'past the respective punch rods A5 and'ASby the toothed roller, not shown,`

but which has been mentioned heretofore Vand adequately described in the Ackerman copending application referred to above. l

The rocker arm `AI1 is operated from a vertically-sliding member AI8, which receives a limited up-and-down movement from a solenoid, (shown diagrammatically as A21 in Fig. 17)` and which is venergized each time a key on the keyboard isdepressed. The punch rod A6 is also op erated by the vertically-sliding member AI 8,V

which, when 'a key is depressed, is forced downwardly, the punch rod A6 making a feed perforation in the tape T. The upward or return stroke of the vertically-moving member AI 8 operates the 'I'he lower roller is `provided'with a row 'of rocker arm jAI1. causing thel pawl'AI associated therewith to rotate the ratchet wheel and, consequently, the associated feed roller, through one.

space; advancingcthe tape.' `This upward'movement of the member AI8 also lifts the punch rod A6 clear of the tape and there is sufficient play between the pawl AI5 and the ratchet y.wheel to permit the punch to clear the tape before the same is advanced. Retrograde movement of the ratchet wheel is prevented bythe detent AIG when the pawl AI5is caused to ride over the teeth'ofthe ratchet on the downward stroke of the member AI8.

The perforators orpunch rods A5 are intended to produce in the tape T, perforations lwhich constitute the symbnilshereinbefore referred to reprec senting the differentmatrices and spacers used inv the slug-casting machine to be controlled by the tape.A The punch rods A5 are mounted and guided' u at their upper ends in the` lower guide Vplate'A!v and at theirlower ends in they block A22, the latter being'recessed'in its lower face to receive a hardened strip A3I,` which servesto sustain the rods at such level that the upper' ends thereof are located in proper spaced relation below the tape T. 'Ihe severalpunch rods A5 are operatively connected'by suitable means to as many different magnets A33, which latter are capable of func-` tioning' independently of ,each other in operating' the punch rods to produce the symbols in the tape. The magnets are energized through'sepa- `rate circuits controlledby the keys CI on theA keyboard C in a manner to be hereafter explained,k and their connection with the punch rodsA5 is.

such that when `a magnet isv energized its associated punch rod will function to perforate the tape.

Thefkeyboard (see Fig. 2)l vis preferablyV iny sulated from the bed plate' O, to which it is secured, and comprisesgenerally a top plate C6,'a

bottom plate C1 andv two side plates C8. The

finger keys CI are in the forrnyof verticallydisposed push rods, projecting downwardly through the top plate C6 and provided with collars or shoulders c which are held resilientlyy engaggedv with the lower face of said plate under tension of light compressiocliV springs cI surrounding the rods and locateddirectly beneath the key buttons. The lower ends lof the key rods CI terminate in the same horizontal plane and are connected respectively through small bell crank'lever's C9 to a corresponding series of fore and aft key barsCIO, which are suspendedA near their rear ends by links CII from the cross member of brackets CI2 depending from opposite sidesof the top plate ,C6. These keybars CID present portions CI3 inclined upwardly toward the rear, so that these inclined portions, yfor' 'o Y reasons presently to appear, will be movedV edgewise as the key bars,l through the links CII and bell cranks C9, are swung rearwardly by the depression of the finger keys CI (see dot and dash lines in Fig. 2). The springs cI associated with' the keys are adapted, of course, when the keys are released, to restore the parts .to' theiru normal position. l

The keyboard mechanism alsov includes' a Vvertically-disposed rocker plate CI4 hingedly connected at its lower'I edge to the fixed bottom plate C1 and extending longitudinallyracross the keyboard with'its front face in contact with the rear ends of the -key bars CII). The plate CI! is resiliently held against the bars CII! by vmeans of a spring CIB (the end onlyv of which is shown in Fig. V2), and, at the right of the plate, a.' stop screw CI1 is provided which limits the forwww-, inve...

lWhile the symbo1s thus ,produced in the. tape are capable of .releasing the matrices' andspacer's` they represent,"theproblem to be solved,` asprevi-M, ously.,v stated, `is that )of accurately determining4 the number of symbols which 'should be produced in the tape to represent a composed linefof Ymat i y y 'rices and spacers of fagivenlength; The present c invention is intended to meet this situation by combining with thel tapeperfor'ating unit A a measuring device B, and by operating themeas-` zoff uring rdevice from the keyboard C through inter-v` mediatecmechan'ism later tobe described, `such that as veach symbol is produced ein the tape a dummymatrix or indicator `'corresponding in thickness to the matrix or spacer represented by saidvsymbol-is presented to the, measuring device, and the results of the measurements accumulated additively by a vsuitable mechanism andfindicated to .the operator. I n this -way,-whatever fthe. length voi' line may be the required number jo! symbolsproduced in the tape will be automatical# ly` determined Whenlthey pointer, inview'of the operator, has traveled through a predetermined distance which'has been selected as the length r o1' the line.

Referring to Figs. 2, 5, and6, it will be'ob-ff served that .the frame of thefmachine; comprises two upright members ,BIZ at the sides thereof and a cross member B9 extending between Vthe said uprightmembers across the rear ofthe machinel at the top.v A set of vdumm'ytmatricesfor cured thereto by means of screws B l3, `so that the rack is readily removable. to facilitate the employment of 'different sets of dummy matrices or indicators corresponding to the different matrix fonts used in a linotype machinaf yAs mentioned heretofore, these dummy matrices correspond injv thickness or are proportionalv tothe thicknessof the matrices orspacebandsbeing used in the lin-V otype machine to be operated bythe tape'. A type of rack whichvmay belusedis shown indetail in Figs.7 and 8. Here it will be seen that the dummy matrices are slidably mounted infslots BM in the base BIS of the rack and in slotslBl in the topl plate Bil, .the said slots Vserving toV guide the dummy matricesintheir vertical move-- ment. It is desirable thatsome means' be provided to retain the dummy matrices intheir proper positions `in the rack whenchanges ofiont aree.- necessary, and for this purpose a rern'oviaible'.barv` BIB may be clamped .along-the topo! the rack@ to retain the dummy matrices in the rack when asv mf Y The manner shown for Y' the purpose of conservingspace.

The measuring rod for the dummy matrices is mounted above the rack, and as akey CI' is de y pressedv the corresponding dummyy matrix is' raised and presented thereto. vThe means for raising the dummy matrices comprise reeds BI9, which'are in some respects similar to the reeds used in an ordinary linotype machine for operating the matrix escapementmechanism. VDue to the staggering of the dummy matrices every alternate reed has an voffset portion B20, whichA is guided at'its upper Yend in'a slot B2I inthe base of the dummy matrix rack, and at its lowerend in a slot in the cross frame member B22 (Fig. 2) The movement of the reeds is limited by a plate B23 projecting into'notches B24. i

In Fig.` 6 it will be observed that the relation of the reeds and dummy matrices is such that when a reed is actuated upwardly the dummy v matrix associated therewith isA likewise projected upwardly intovthe path of the measuring rod, which may be a toothed bar B25- As each reed corresponds to a different symbol: ofthe perforated tape', the dummy matrix associated therewith will correspond in `thickness to the correspondinfg matrix of the linotype vmachine operated by thetape. v

As shwn in Figs. 4 and 5, the measuring bar B25 is pivotally mounted at B26 and B21 on arms B28 and B29. respectively, these arms in turn being pivoted at'B30 and lIB3Ito downward extensions B32 of the frame member BI2. The` matrix rack BI I has astop B33 at the left which limits the movement of the measuring bar B25 in this direction, arid thebar 'is normally held against this stop' by means of a spring B34 connectedv to the frameat VB35 and to a pivoted link member B36, which latter has a U-shaped slot B31 at its upper end engaging a pin B38 on an angular-shaped bracket B39 flxedly secured to the measuring' bar B25. The lower end of the link B36 is pivoted at B40 to a slidablelink member B4I shown in Figs. 4 and 10. This member is fastened to a frame element B42 by pin and slot connections B43 and B44, and has a toothed rack B45 on its upper edge adapted to mesh with a gear B46 pinned to a shaft B41 mounted between the frame members B42 and B48 (Fig. 2). The

-frame member B42 is a plate fastened in suitable manner to tne upright frame members BI2 at :both sides of the machine, as by screws B49,

while the frame member B48 :is mounted in spaced relation therewith by spacer plates B50 and screws B5I.

It is apparent that any movement of the pivot point B40 of the link B36 will be imparted to the gear B46 through the link B4I,'and this motion is in turn transferred through suitable gears B52, B53 and B54 to the gear B55,.on the latter of which is an arm B51 carrying ypawls B58 and B58' held by means of springs B59 and`B59' in engagement with a ratchet wheel B60. Gear B55 idleson the shaft B6I which is journaled in the frame member B42 and a lbracket extension B62 on the frame member B48. The ratchet wheel B60 is pinned to this shaft, however, so that any rotation thereof is imparted to a worm B63 (Figs. 3' and 4)also pinned to the'shaft. Theworm engages a worm wheel B64l pinnedl to a vertical shaft B65, which'has its bearings in bracket extensions B66 and B61 of the frame member B48. A clutch is also mounted on the shaft B55 consisting kof twoengageable notch@r faced members" B68 and B69, the .first beingcf splined to-the shaft-so as -to be slidable 'axially therewith, and the second loosely..mounted.onthe shaft, vso thatwhen lthe two'members are.' eng'agedfthe rotation ofthe shaft is impartedjto the lower member. The two clutch elements are normally held'tin engagement by a spring B18,

but are adapted to be disengaged byy an'arm B11,` f 10 which'has ldiverging prongs carrying pins extend-.1

top clutch member B68. As shown in Figs. 2,3,

and 4, thearm :B1Ifcontrolling the? engagement.,

and disengagement of the clutch is pinned ltora rodr-B13'journaled inextens'ions B14 and B15. of theframe bracketB61." 'The rocking of this` to the shaft atvthe .rightend thereof within easy;A reach ofthe operator. f l rSecured to thelower clutch elementBBLsov as Vto be rotatabley therewith, is a gear wheel B11 adapted to mesh'with'a rack B18 slidably mount-` ed in a vslot B19, also in the frame bracket B61: The rack'carries 1a pointer-indicator P, whichk moves along an em scale B8I, the movement of the rack `being against the 'tension' of a coil spring B82 mounted` at `the bracket B61. f 1 d Referringaga'in .to Figs. 2l and 4', it willbe observed that the link B36 attached to. the measf uring rod has another link B83 pivoted thereto atB84, whichlink at its other end is pivoted'- atiB85 to a lever armB86, the latter `being pivotallyy supported byfthe frame at- B81,-and"`at its lowerend attached byavpin and slot` coni nection B88 to the armature.

vided. f

The' operation' of this''phase of lthe invention i's'now clear. The operator first determines the length of the line to be -composedan'd'sets the pointer PI at thegraduatio'n indicating the proper length. Thev pointer PIU is set so as to coincide with the position ofthe pointer PI`by sliding it-to the proper depression S35." v'I'he initial setting of the scale'for a 30-em line is shown in Fig.A 11. ',ihe'operator now proceeds in the usual maiinerby depressing the keys'C I and, as the dummy matrices are measured in the manner heretofore described, the pointer P 'moves' toithe left tapproaching'the pointer PI. When a'space key'is depressed the pointer P moves through a distance equivalent yto the distance that an unexpanded spaceb'andwould take up in the line. At the same time; however, the reed, which Iis associated withl thef'dummy matrix simulating v'the spaceband rocksvthe leverfSII! by means of the stud'SIS which is lpositioned on the reed, rcausing the arm S I 1 to bero'tated in aclockwise direction, and the pawl S2I associated therewith rotates-the ratchet wheel S22 and, consequently the shaftV on which itis secured. Asl the clutch is engaged, thisrol tation willlbe imparted'to thegear SSI, and as its direction of rotation is clockwise this gear will rdisplace the `rack S32 and, consequently, the pointer PII! to'V the right. The mechanism is so designedthat the distance through which the pointer PI IJ is displaced for each operation of the spacer key is equal to the difference between the Aexpanded and unexpanded thickness'of a spaceband'. Obviously, therefore, when these upointers meet, as shown/in Fig. 12 the sum of the total thickness of thematrices plus the unexpanded thickness of the spacebands used, as indicated by the potent-iai expansibilities of these spacebands, as. indicated by the pointer PIII, will equal the length oi the line desired. The operator may end his line anytime isassured that between these two limits the line when composed ona linotype machine will After the completion of ailine, itis only' necessary for the 'operator' to depress /t-he handle B16. This rocks the shaft 12,13,V thereby disengaging both of the" clutches controllingthe operation of the pointers P and PII). The mannerin which disengagement is accomplished is:v evident from Fig. 2. 1 Upon the disengagement of theclutches,

; the coil springsv B82 and S34 function to return both'the pointers to their initial'po'sitions, thus preparing them for the composition ofthe next line.y

The operation of the machine and the manner in which-the various units cooperate will have been understood from the detailed descriptionl givenabove, but a brief recapitulation may be i helpful. Let it be assumed thata' group of sym-4 bols is to be produced in the tape representing a' line of matrices. If the initial 'character ofthe line is a capital letter, the "key `markedy UC, designating'upper case, is depressed, whereupon the key bar CIU connected therewith isI moved into contact with the conductor bars C2ll,j,tlf1e combination of lwhich will producefa symbol Yin the tape which, when used for operatinga linotype machinewill cause the upper casekey thereof to function. lrour separatecircuitsare energized upon thedepression of a key, The first circuit transmits an electric: 'currentfrom the sourceof energy Y through they conductor bars C24 which are at -that time in contact'with'the bars CID, and `from there to the punch'magnets A33 ,associated 'with the respective conductor bars, and thereafter to ground. The punch rods A5 associated with the magnets A33'arethus actuated'and produce in the tape a perforation conibination or symbol representative ofVUC, which,

as mentioned heretofore, functions 'tofoperate the'` corresponding key'of the linotype'machinewhen the tape is used to operate the same.

The 'second circuit transmits an electric' cur-f lrent from the source 'of energy Y through the same conductor bars to the magnets Ricorresponding' thereto, The locking bars/RlV connect;-

ed to these magnets' are thus shifted to the left" to establish a `releasing combination for'specialv slides somewhat similar to the slides M3, but which function to releasethe master locking bar N heretofore mentioned.

'I'he third circuit transmits a current from theV sourceof energy YA to the solenoid Q3. As this solenoid is energized the retaining bar Q is swung to the left, freeing'the slide controlling the bar N so as to shift the bar N to the left to lockithe group of slidesv M3 controlling the lower case characters and to unlock the sli es controlling the uppercase characters:

The fourth circuit transmits a current from the source of energy Y to the feed solenoidwhich operates the overhead punch A6 (Fig. 1), which is thus actuated toproducevin `the tape afeed perforation whereby the tape T is advanced' one step by the subsequent actuation of the'pawl and ratchet devices A14 and AI5.

In the foregoing operation, the only units brought into .play are the keyboard and vperforating mechanism. However, when a key bearing a character, as, for instance, a letter, is de-v pressed, the same circuits will be-established, differing, however, in the combination of magnets A33 rendered operable to'produce inlthe tape a symbol corresponding to the said letter. Simultaneously therewith, magnets R4 are energized, which operate to-'shift the proper locking allowed tol rise under the influenceof vits springactuating means M8 and trip thecam yoke assoelated therewith. Asthe yokefrises it 'lifts' the overlying" reed I113| 9, Y thus! causing the ,d y,
